Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

Excited atoms lead to exciting lessons! Learners use heat and light to excite both atoms and molecules. They display their learning in the form of Bohr models depicting the excited state of the atoms.

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

It's all relevant, really. Individuals use the scientific method to learn more about elements, atoms, and their placement on the periodic table. They conduct experiments using materials common in nature to explore how elements affect our...

Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

Try not to blind anyone with science by following the safety rules. The lesson encourages scholars to form an ionic compound from magnesium and chlorine. Then they determine the empirical formula and determine the mole ratio and percent...

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Light a fire in your pupils! Scholars conduct a flame test and observe the emission spectra of several different salts in an enlightening hands-on investigation. They use their observations to make comparisons and conclusions about the...

For this atoms worksheet, high schoolers compare sub-atomic particles' position, relative charge, and relative mass. High schoolers define mass numbers and atomic numbers. This worksheet has two graphic organizers and four short answer...

Students complete two graphic organizers in this ionization worksheet by filling in the proton number for given elements. Then, they create two graphs plotting the first ionization energy against the proton number.

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Certain materials do not always maintain the same physical properties when they exist in the nanoscale. Help your classes to explore this idea through an experimental lesson. Scholars use spectroscopy with samples of silver solution...

From molecules to nanotubes, an engaging unit explores the world of tiny science. Fifteen hands-on experiments and lessons engage young scientists as they learn chemistry. Discussions, worksheets, and data analysis reinforce the concepts...

Accommodate your chemistry class with an experiment that is both entertaining and educational. Through the activity, blossoming chemists perform calculations on various isotopes, as represented by beans and legumes, to obtain...

No practice problems are given on this handout; it is a detailed list of concepts to know and tips for working related problems in chemistry. Give this to learners as a study guide, or use it early in your career as a chemistry...

Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.

Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

In this electron arrangement activity, students complete two graphic organizers by determining the proton number of given elements from their first ionization energy. Then, they plot graphs of the first ionization energy against the...

Candy is one of my favorite words, and it's an even better word when it relates to science. Yes, candy science can happen when you grow rock candy crystals with your class. The entire process for growing these edible wonders of nature is...
